December

Renters live with unanchored furniture because they can't drill.

Your heat comes from burning fuel, which means your house makes carbon monoxide on purpose all winter and exhausts it on purpose — until something interferes: a cracked heat exchanger, a blocked flue, a backdrafting water heater sharing the chimney.

Extension cords are for Saturday projects, not infrastructure.

Everything in a modern house has a circuit board in it now — the furnace, the water heater if it's fancy, every appliance with a display.

Here's the thing your semiannual button-test can't tell you: the test button proves the battery and the horn work — not the smoke sensor.

Insurance claims run on evidence, and the evidence has a deadline nobody announces: it must exist BEFORE the bad day.

December stacks every indoor fire ingredient into one week: a drying evergreen in the living room, open flames on the mantel, the year's most ambitious cooking, and a house full of distraction.

Your house's era means some or all of its wiring predates modern grounding.

Fire escape planning upstairs comes down to one question: if the stairway is full of smoke, how does each person in each bedroom get down?

Every water disaster starts as a drip you couldn't see: the washing machine hose weeping behind the machine, the water heater rusting through at the base, the supply line sweating inside a vanity.

Radon is a naturally occurring radioactive gas that seeps up from the soil into homes — you can't see it or smell it, and the only house that has a radon problem is one that's been tested and confirmed.

Heat pumps do things in winter that LOOK broken to anyone raised on furnaces, and with ~60–120 freeze days a year in your county, yours will do all of them.

You told us you're not sure what kind of water heater you have — join the club; it's the appliance people interact with least and depend on most.

Water heaters ship set by a factory that has never met your household.

Someday — a burst washing machine hose, a split supply line, a frozen pipe letting go — water is going to be spraying inside your house, and every minute it runs costs you real money.

A house your age has a sewer lateral made of whatever the year offered, and none of the options aged gracefully.

Every toilet and faucet in your house is fed by a small flexible line, and if those lines are gray or black rubber, each one is a little time bomb with a 5–10 year fuse.

You told us you don't know your roof's age — totally normal, most homeowners don't, and nobody hands you a binder at closing with this stuff filled in.

You have gutter guards, which means someone — maybe you, maybe the last owner — bought a reduction and was probably sold an elimination.

Doors and windows move, sag, and shrink with every season; their seals age out quietly.

Your winter-prep card works to keep this day from coming; this card is for when it comes anyway.

Two risks share this card.

Snow load panic sells a lot of unnecessary shoveling, so here's the honest math: fresh powder weighs 3–5 pounds per square foot per foot of depth, and most roofs are built to carry 30–40 pounds.

Every key to your house that existed before closing day is still out there.

You've never actually tested this house's windows and doors — the inspector opened a sample, the sellers stopped noticing years ago.

Every major system in your house has its birthday stamped on a data plate — usually encoded in the serial number — and knowing those dates changes how you spend money for the next decade.

Of everything you inherited from the sellers, the HVAC filter is the item you can reset to factory-new for ten bucks — and one of the most revealing.

Your house has a paper trail, and the first weeks of ownership are when it's easiest to collect — the sellers' agent still answers email, the sellers still remember their vendors, and warranty-transfer windows (some manufacturers give you 60–90 days) are still open.

Somewhere on your property are capped pipes that exist purely for the worst day your plumbing will ever have — and the middle of a sewage backup is the wrong time to learn they exist.

Your breaker panel is the index to your whole electrical system, and right now it's either blank, or — worse — labeled by someone else's memory of a renovation two owners ago.

That red cord hanging from your opener rail is the manual override, and it has a technique.

Your first full month of bills is a diagnostic report about the house, disguised as junk mail.

Everything else on your punch list generates paper and photos: lock receipts, breaker maps, detector dates, meter shots, serial numbers, permit printouts.

You don't know when these detectors were tested, how old they are, or whether the sellers' painter took the batteries out in 2019 and never confessed.

Your find-the-shutoff card covered the inside of the house.
